It's about "matters of love," and also about "love that matters." The love that matters -- or should -- involves two married couples. Both unions are sorely threatened by an adulterous relationship. Annette O'Toole and Griffin Dunne play the husband and wife whose already shaky marriage is made shakier when second couple Tony Goldwyn and Kate Burton enter the scene, followed shortly thereafter by Goldwyn's mistress Gina Gershon. Love Matters debuted October 3, 1993, on the Showtime Cable Service.
